The utility model relates to the technical field of regional
sponge city construction, in particular to an automatic rainwater collection, natural purification and autonomous recycling
system which comprises a rainwater drainage
pipe network, the rainwater drainage
pipe network is separated from a first municipal rainwater drainage
trunk line through a
gate valve, and one side of the rainwater drainage
pipe network is connected with a
water collection pool through a
water diversion pipe. A control mechanism is installed in the water collecting
pool and connected with a
control unit and a water collecting pipeline, the water collecting pipeline is connected with an artificial water
system, the other side of the artificial water
system is connected with an overflow pipeline, the overflow pipeline is connected with a second municipal rainwater drainage pipeline, and a circulating water pump is installed in the artificial water system. According to the system for automatically collecting, naturally purifying and autonomously recycling the rainwater, the rainwater is automatically collected, naturally purified and autonomously recycled, all indexes of the collected rainwater meet the
greening environment landscape water standard, the garden
greening irrigation cost and the environment landscape
water cost are greatly reduced, and the environment landscape water utilization cost is greatly reduced. The method is an effective way for assisting
sponge city construction and carbon
neutralization.
